No. 828,525 Int. Cl. E04h 1/00, 1/04 US. Cl. 52236 15 ClaimsABSTRACT OF THE DISCLOSURE A dwelling unit of substantially fixed floorplan has front, rear and opposite side boundary walls enclosing adwelling space embracing a peripheral area surrounding a rectangularcenter area. Fixed peripheral wall means in the peripheral areacooperate with said boundary walls to provide: along each front wall, apair of front corner rooms separated by an access hall; along each rearwall, a pair of rear corner rooms separated by a pair of back rooms;and, along each side wall, an outer bathroom and an innertransversely-extending bathroom corridor, the bathroom separating andthe corridor interconnecting adjacent front and rear corner rooms. Fixedcenter wall means in the center area provide a closet wall, extendinglongitudinally from one bathroom corridor to the other, and cooperatewith said peripheral wall means to provide a pair of similarly-extendinghall and center corridors, respectively extending along the front andback sides of the closet wall, the front-hall corridor passing through apair of access doorways, one for each front corner room.

The foregoing dwelling unit provides one large apartment having a fixedfloor plan, which embraces 6 rooms, 2 baths and an access hall. Byinstalling a removable closure across the middle of the center corridor,said unit provides a pair of 3 room, 1 bath apartments, each accessiblefrom the access hall. By locating that removable closure across eitherend of the center corridor, one apartment is reduced to 2 rooms, theother increased to 4 rooms.

BACKGROUND OF THE INVENTION Field of the invention This inventionrelates to improvements in fixed floorplan dwelling units.

Description of the prior art In planning low cost apartment buildings,it is often desirable to provide for one, two, three and sometimes 4bedroom apartment units and more or less necessary to use fixed floorplans which, to a large extent, restrict each apartment to a fixednumber of rooms. This has forced the designer to guess as to how manyapartments he should provide in each different fixed-room category. As aconsequence, when the apartment is built, the owner may be faced withthe problem of modifying the fixed floor plans of one or more apartmentsto meet a current demand for apartments having a smaller or largernumber of rooms.

It has been proposed heretofore, to solve this problem (or a relatedone) through the use of one or more shiftable partitions. Thus theDavison Pat. No. 2,372,768 confines the fixed load-bearing walls of thehouse to the external boundary walls thereof and sub-divides theenclosed space through mobile wall panel units as desired. The RobertsonPat. No. 2,752,675 uses castered closetproviding mobile wall units forstorage-space providing and room sub-dividing purposes. The Dadrus Pat.No. 3,055,061 employs mobile interior walls which can be arranged andrearranged with the same ease as furniture. The Van der Lely Pat. No.3,292,327 provides modular box car units which can be arrangedside-by-side to provide habitation space on a single floor andsuperimposed to provide plural floors. None of these solutions areentirely satisfactory.

SUMMARY OF THE INVENTION Objects of the invention The principal objectsof the present invention are: to avoid the necessity of planning inadvance to provide a proposed apartment 'building with a fixed number ofapartment units in each of several different fixed-room categories; toavoid the necessity of fixing the number of apartment units it shouldhave in each different fixedroom category; and to provide for amultiplicity of fixed floor plan apartment units which can be easily,quickly and simply made to function, at one time, as one large apartmentand, at another time, as two smaller apartments of equal or unequal sizeand thereby accommodate the current demand for smaller or largerapartments without significant modification either of any apartment orof any basic floor plan.

Other important objects of the present invention are to provide: anapartment unit having a fixed basic floor plan, which, while containingfixed walls delimiting fixed rooms interconnected by fixed corridors,provides a flexible arrangement that can be easily, quickly and simplymade at one time to function as one large apartment and, another time,to form two smaller apartments of equal or unequal size; and toaccomplish the foregoing objects without necessarily modifying any ofthe fixed structural elements of the building.

Another important object is to include, in said fixed basic floor plan,the provision of utility connections permitting the optional location ofa kitchen within either a front or back room without requiring anyappreciable modification of any fixed structure of the basic design.

Statement of the invention All of the objects of my invention areachieved in a fixed floor-plan dwelling unit which is constructed inaccordance with the preferred embodiment of my invention, this preferredunit comprising: (A) front, rear and opposite side boundary wallsenclosing an apartment space having a rectangular center area and asurrounding peripheral area; (B) fixed peripheral wall means in theperipheral area cooperating with said boundary walls to provide, (1)along each front wall, a pair of front corner rooms separated by anacess hall, (2) along each rear wall, a pair of rear corner roomsseparated by a pair of back rooms, and (3) along each side wall, anouter bathroom and an inner transversely-extending bathroom corridor,the outer bathroom separating and the inner corridor transverselyinterconnecting adjacent front and rear corner rooms; (C) fixed centerwall means in the center area providing a closet wall extendinglongitudinally from one bathroom corridor to the other and cooperatingwith said peripheral wall means to provide a pair of similarly extendinghall and center corridors respectively along the front and back sides ofsaid closet wall, said front-hall corridor passing through a pair ofaccess doorways, one for each front corner room; and (D) means framing,across said back-side center corridor, an opening which, when saidapartment space is to be used as a double bathroom apartment,interconnects the space on its opposite sides, and which, when saidapartment space is to be divided into a pair of single bathroomapartments, is arranged to receive a removable apartment separatingclosure.

BRIEF DESCRIPTION OF FIGS. 1AC AND 2 Boundary walls The floor plan ofthe entry level unit shown in FIG. 1B comprises: fixed front, rear andopposite-side boundary walls 1, 2, 3 and 3' enclosing an apartment spacehaving a rectangular center area and a surrounding peripheral area. Thisapartment space is divided into somewhat identical halves on oppositesides of the transversely extending vertical plane indicated by line 44.

Wall means in peripheral area Fixed walls 6, 7, 8, 9 and 10, in the lefthalf of the peripheral area and 6', 7', 8', 9' and 10 in the right halfof the peripheral area, cooperate with said boundary walls 1-3 and 3 toprovide: along each front wall 1, a pair of front corner rooms 12, 12,separated by intervening space including a stairwell 13, 13; along eachrear wall 2, a pair of rear corner rooms 14, 14 separated by a pair ofback rooms 15, 15' and, along each side wall 3 (3') an outer bathroom 16(16) and an inner transversely-extending bathroom corridor 17 (17'). Theouter bathroom 16 (16) separates, and the inner corridor 17 (17')transversely interconnects, the adjacent front and rear corner rooms 12,14 (and 12', 14).

Wall means in center area A fixed wall 20, extending longitudinallythrough the left and right halves of the center area, provides a closetwall 20 extending longitudinally from one bathroom corridor 17 to theother 17'. This longitudinally-extending closet wall 20 cooperates withthe fixed wall means in the peripheral area to provide a pair ofsimilarlyextending corridors, namely front hall corridor 21 and centercorridor 22, respectively, extending along the front and back sides ofthe closet wall. The front hall corridor 21 passes through a pair ofaccess door-ways 23, 23, one for each of the front corner rooms 12, 12'and may be viewed as extending up to and interconnecting the bathroomcorridors 17, 17' on the front side of the closet wall 20. The centercorridor 22 passes through the center doorway 24 and left and rightdoorways 25, at oppo 4 site ends of the center corridor 22 so as tointerconnect bathroom corridors 17, 17'.

Framing means Each of the (front-side hall corridor) doorways 23, 23'and of the (back-side center corridor) doorways 24, 25 and 25, ispreferably provided with means (not specially indicated) framing itscorresponding corridor opening. When the entire apartment space is to beused as a large two bathroom apartment, each of the doorways 24, 25 and25' may be left open (or provided with regular access doors) so that thecenter corridor 22 is usable throughouts its extent, while one of thedoorways 23, 23, in the front-side hall corridor 21, may be providedwith regular access doors and the other with some form of removablenon-access closure, such as a removable wallpanel structure designed forsnug mounting within the doorway.

Since the entire apartment space may be optionally used to provide twosmaller single bathroom apartments, such apartments must be separated.Therefore, in further accordance with my invention, each of the framingmeans for at least two (and preferably all three) of the doorways,across the center corridor 22, is arranged to receive a removableapartment-separating or non-access closure, such as a removablewall-panel structure (not shown) designed for snug mounting within thedoorway. In place of a removable wall-panel structure, one may use adouble door closure such as is shown in FIG. 2. Here double doors 26,26' are removably mounted in said doorway 24 of the center corridor 22to divide the entire apartment space into two smaller single-bathroomapartments of equal size. The location of the doors 26, 26 are indicatedin FIG. 1B by a pair of dotted lines.

Alternatively, the said apartment-separating closure 26, 26' may bemounted in door way 25 to divide the entire apartment space into twosingle bathroom apartments of unequal size, the smaller one bath tworoom apartment being located entirely in the left half of the apartmentspace. On the other hand, if appropriate framing means is mounted indoorway 25, then the smaller of the two apartments may be provided inthe right half of the apartment space by mounting saidapartment-separating closure 26, 26' in doorway 25'.

Outside access to and from all apartments of FIG. 1B is provided throughdoorway 27 in front boundary wall 1 and left corridor 28 between fixedwall 6 and stairwell 13. This street-access corridor may, of course, beprovided (on the right side of plane 44) by spacing fixed wall 6' fromstairwell 13' and providing it with a doorway corresponding to doorway27.

Kitchen utility connections Each of the walls 7, 8 of each bathroom 16,16' is preferably provided with permanent (fixed) kitchen utilityconnections, which are indicated by drawing these walls in triple linesrather than double lines. With this dual utility connection arrangementprovided in both walls of each bathroom, the kitchen may be located inany one of the four corner rooms when all of the apartment space is usedas a large Z-bathroom apartment. When the entire apartment space is usedas two apartments, the provision of dual kitchen utility connections ineach apartment permits the kitchen to be optionally located (temporarilyor permanently) in the front or back corner room of each apartment or inthe front corner room of one apartment and the back corner room of theother.

Flexibility It will be appreciated that the fixed floor-plan dwellingunit shown in FIG. 1B is quite flexible in that it optionally provides(a) one large apartment, or (b) two smaller apartments of equal size,one on each side of lines 4-4, or (c) two smaller apartments of unequalsize with the smaller apartment being provided on either side of line44. Since the dwelling unit shown in FIG. 1B comprises 6 rooms and 2baths, the larger apartment would be of that size, each of the equalapartments would have 3 rooms and 1 bath while the larger and smallerapartments would have 1 bath each and 3 rooms and 1 room respectively.

Naturally the use to be made of the rooms of any given apartment dependsupon each particular occupant. In the large 6 room 2 bath apartment, forexample, a front corner room 12 may be used as a living room, thecorresponding rear corner room 14 as a kitchen and the 4 remaining roomsas 4 bedrooms or a den and 3 bedrooms or otherwise. Since the frontcorner rooms 12, 12' are fairly large, one (or both) of them may readilybe partitioned into 2 rooms for whatever uses may be desired. Otherrooms may be partitioned as desired, 1

The fixed basic floor-plan used in FIG. 1B lends itself to multifloorapartment buildings such as the three-level building exemplified by thelower level unit shown in FIG. 1A and the upper level unit shown'in FIG.1C in combination with the entry level unit shown in FIG. 1B. It will beunderstood that the lower and upper level units of FIGS. 1A and 1C are,for all practical purposes identical to the entry level unit of FIG. 1B.The street corridor 28 of the entry level is not required in the lowerand upper levels; hence fixed wall 6 in each of the lower and upperlevels, is located immediately adjacent the left side of stairwell 13.

The fixed basic floor-plan, characterizing each of the units of FIGS.1A, 1B and 1C, lends itself to modular construction, such as is proposedin U.S. Pat. No. 3,292,327. Thus each unit may be constructed in theform of 3 modular elements comprising: one front element; a backelement; and a center element; each of said modular elements extendingfrom one side wall 3 to the opposite side wall 3'. Alternatively, it maybe constructed in the form of, say, 4 modular elements comprising: aleft element along side wall 3; a right element along side wall 3; andtwo more or less equal parallel elements therebetween.

FIG. 3 MODIFICATION The flexibility of the fixed basic floor-plandescribed in connection With- FIGS. lA-C is further illustrated by FIG.3 wherein two such basic units are arranged in sideby-side relationshipand interconnected through a doorway in their adjacent side walls (i.e.their common wall 3) to provide: (a) one large 12 room 4 bathroomapartment; or (b) two apartments respectively having either 1 and 3bathrooms or 2 and 2 bathrooms; or (c) three apartments having 1, 2 and1 bathrooms; or (d) four apartments each having one bathroom.

The 6 room unit on the left half of FIG. 3 corresponds to the lowerlevel unit of FIG. 1A; hence it bears identical designating numbers;thus, 12 and 12' in FIG. 1A are 12 and 12 in the left half of FIG. 3.The right half of FIG. 3 has the same basic 6 room, 2 bath floor plan asthe lower level unit of FIG. 1A but some differences are dotted in. Forthe sake of clarity, the left and right side boundary walls of the righthalf of FIG. 3 are designated as 3 and 3", respectively, while its fixedwalls, rooms and corridors are assigned designating numberscorresponding to those used in FIG. 1A except they are 100* numbershigher. For example, 12 and 12' in FIG. 1A are 112 and 112' on the righthalf of FIG. 3.

The wall 3' of FIG, 3 is provided with an interconnecting doorway 130which, for interconnecting purposes, may be left open or provided with aregular access door. It is also arranged to receive a removableapartment-separating closure of the removable wall-panel type or of thedouble door type illustrated in FIG. 2. With the doorway 130 open oropenable, the space between corridors 21 and 121 functions as aninterconnecting corridor 131.

It will be understood that, in an apartment building, each half of FIG.3 has the framing means, the kitchen utility connections and theflexibility of any unit constructed in accordance with the preferredembodiment of my invention, hence characterized by the fixed basic floorplane described in connection with FIGS. lA-C. In addition, greaterflexibility comes from the fact that a single apartment may occupy spaceon both sides of center wall 3. Finally, it may be constructed inmultiple level buildings and in modular units.

The FIG. 3 arrangement is well suited for use in college dormitories,military barracks, and other like segregated or unsegregatedconstructions requiring a large number of sleeping rooms or bedroomsrather than apartment units with kitchens. For college dormitorypurposes, the large room 112' of FIG. 3 could be used as a common roomor lounge or subdivided, while most (if not all) of the 11 remainingrooms, could be subdivided by (fixed, movable or removable) walls orpartitions to provide a greater number of rooms to be used for variouspurposes, such as sleeping rooms, study dens, chaperone apartments, etc.Like considerations would apply to military base barracks where thelargest number of sleeping rooms in a given unit is a primeconsideration.

THE FIG. 4 MODIFICATION This figure illustrates that, the basic floorplan remains to a large extent unchanged when a wall, corresponding towall 9 in FIG. 1C, is omitted to provide a larger corner room 14",covering the area normally occupied by rooms 14 and 15. Furthermore, ifthe FIG. 4 arrangement is located at the lower'or upper levels of a 3level structure and if it is to be occupied more or less permanently byone family or one group, then the access door may be located at one endof the stairway, which connects it to the adjacent floor, or at astairway landing between floors. Thus the doorway 134 in FIG. 4 islocated at the stairway landing.

THE FIG. 5 MODIFICATION The FIG. 5 arrangement incorporates the basicfloor plan in a single floor duplex having entrance doorways 137 and 138adjacent the center of the front wall 1. In this figure, one wall 6" notonly separates the front corner rooms 12 and 12 but it also may be saidto eliminate the hall corridor 21 on the front side of closet wall 20because it cuts that corridor in half and prevents direct access betweenthe duplex units. This design however retains a high degree offlexibility because it retains corridor 22 which can be blocked off atits center to provide duplex units of equal size or blocked oif ateither end to provide a small two room duplex unit and a larger 4 roomduplex unit. The dotted lines in rooms 12 and 12' represent kitchenequipment and a partition wall and in room 15 represents a partitionwall.

FIG. 6- MODIFICATION The arrangement of FIG. 6 illustrates the samebasic floor plan in a single dwelling unit having a single frontentrance doorway 140'. The advantage of a unit of this type resides inthe ease with which it can be converted into a duplex unit of equal orunequal size. For example, a conversion of this character into duplexunits of equal size requires only the provision of another accessdoorway 140, the installation of a removable apartment separating closer26, or 26" in doorway 24 and the installation of another likeapartment-separating closure across corridor 21 at a doorway designated141.

MISCELLANEOUS While I have described and illustrated the provision ofoutside access through the front boundary wall 1, it will be appreciatedthat outside access may be provided through the boundary walls whereverdesired, but access through the front half is preferred over access tothe back half. The precise location of outside access normally is amatter of choice for the designer; hence, a particular location ofaccess is not essential although, again, centrally-disposed outsideaccess through the front boundary wall is normally preferred.

Also while the kitchen utility connections preferably are located in thefront and rear bathroom walls, it will be obvious that they may, in somecases, be advantageously located in an adjacent portion of the adjacentboundary wall.

In FIG. 3, a common wall 3 between units with an interconnectingpassageway 130, as shown, is preferred. However, spaced walls 3', 3 forthe left and right dwelling units, respectively, may be employed with aninterconnecting tunnel-like passageway therebetween.

In FIG. 4, the left end of the back-side corridor 22 may be separatedfrom back corner room 14" by a partition.

In FIG. 5, the wall 6 may be provided with a removable room-separatingclosure across the path of the frontside corridor 21 for conversionpurposes. The same is true of FIG. 6 at doorway 140.

In this application, I have spoken of a rectangular center area. This,however, is not essential. As will be obvious, it may be of oval shapeor of any other convenient equivalent shape. Likewise, the wall 20 inthe center area is referred to as a closet wall. Again, it will beobvious that a wall having closets may be desirable i but not essential.Any desirable form of separating wall in the central area may be used asthe full equivalent of closet wall 20.
